PET detects changes in metabolism between task periods and is thus insensitive to areas that are activated during all or most of cognition. Depth-recorded, evokedpotentials indicate that many multimodal and limbic cortical areas may be activated during most cognitive tasks. Thus, PET may be insensitive to some core processes of awareness that are difficult to eliminate from the control periods.

Jessica du Toit wonders if our relationship with our pets can be morally defended.

This study examined preschool children’s reasoning about and behavioral interactions with one of the most advanced robotic pets currently on the retail market, Sony’s robotic dog AIBO. Eighty children, equally divided between two age groups, 34–50 months and 58–74 months, participated in individual sessions with two artifacts: AIBO and a stuffed dog. Evaluation and justification results showed similarities in children’s reasoning across artifacts. In contrast, children engaged more often in apprehensive behavior and attempts at reciprocity with AIBO, and more (...) often mistreated the stuffed dog and endowed it with animation. Discussion focuses on how robotic pets, as representative of an emerging technological genre, may be blurring foundational ontological categories, and impacting children’s social and moral development.

'When I play with my cat, who knows if I am not a pastime to her more than she is to me?' - Michel de Montaigne. Why do we live with pets? Is there something more to our relationship with them than simply companionship? What is it we look for in our pets and what does this say about us as human beings? In this fascinating book, Erica Fudge explores the nature of this most complex of relationships and (...) the difficulties of knowing what it is that one is living with when one chooses to share a home with an animal. Fudge argues that our capacity for compassion and ability to live alongside others is evident in our relationships with our pets, those paradoxical creatures who give us a sense of comfort and security while simultaneously troubling the categories human and animal. For what is a pet if it isn't a fully-fledged member of the human family? This book proposes that by crossing over these boundaries pets help construct who it is we think we are. Drawing on the works of modern writers, such as J. M. Coetzee, Elizabeth Marshall Thomas and Jacques Derrida, Fudge shows how pets have been used to think with and to undermine our easy conceptions of human, animal and home. Indeed, "Pets" shows our obsession with domestic animals that reveals many of the paradoxes, contra - dictions and ambiguities of life. Living with pets provides thought-provoking perspectives on our notions of possession and mastery, mutuality and cohabitation, love and dominance. We might think of pets as simply happy, loved additions to human homes but as this captivating book reveals perhaps it is the pets that make the home and without pets perhaps we might not be the humans we think we are. For anyone who has ever wondered, like Montaigne, what their cat is thinking, it will be illuminating reading. (shrink)

Pets often factor in older adults’ health behaviors and decisions. However, the degree to which issues related to pet ownership are encountered or addressed by professionals working with this population remains unknown. The aim of this study was to identify specific issues stemming from pet ownership professionals had encountered in their work with older adults, people living with dementia, and care partners. An interdisciplinary sample completed an online survey addressing pet ownership issues encountered in their work. Descriptive statistics, t-tests, (...) and repeated measures ANOVAs were used to analyze quantitative data. A conventional content analysis was used to analyze open-ended responses to an item asking about “other” issues encountered in their work with these populations. The professionals estimated 46.29% of clients had been pet owners, 41.23% regularly asked about pets, and 79.22% had encountered issues related to pet ownership. Specific issues raised to the professionals varied by type of client. The professionals reported older adults most often raised getting pet items into the home and concerns about their pets’ health. The issues most often raised by people living with dementia to the professionals were planning for the pet due to a housing transition and basic pet care. Care partners focused on basic pet care and planning for the pet due to a housing transition. The professionals themselves most often raised the issues of basic pet care, concerns about falling, and the pets’ behavior. Professionals who entered clients’ homes were more likely to raise issues stemming from pet ownership compared to those who reported they did not enter clients’ homes in their current job, t = 5.59, p < 0.00001. The eleven new issues identified by the content analysis underscored how the health and wellbeing of people and their pets are linked. The results of this study provide strong evidence that professionals do encounter issues related to pet ownership. Including issues stemming from pet ownership into procedures, policies, and programs is likely to have positive impacts on those served by and working in the geriatric workforce. (shrink)

New research tools such as PET can produce dramatic results. But they can also produce dramatic artifacts. Why is PET to be trusted? We examine both the rationale that justifies interpreting PET as measuring brain activity and the strategies for interpreting PET results functionally. We show that functional ascriptions with PET make important assumptions and depend critically on relating PET results to those secured through other research techniques.

Not so long ago, any form of sexuality not leading to the conception of children was seen as, at best, wanton lust, or worse, a perversion. One by one, the taboos have fallen. The idea that it could be wrong to use contraception in order to separate sex from reproduction is now merely quaint. If some religions still teach that masturbation is "selfabuse," that just shows how out of touch they have become. Sodomy? That's all part of the joy of (...) sex, recommended for couples seeking erotic variety. In many of the world's great cities, gays and lesbians can be open about their sexual preferences to an extent unimaginable a century ago. You can even do it in the U.S. Armed Forces, as long as you don't talk about it. Oral sex? Some objected to President Clinton' choice of place and partner, and others thought he should have been more honest about what he had done, but no one dared suggest that he was unfit to be President simply because he had taken part in a sexual activity that was, in many jurisdictions, a crime.

One method for investigating the neurobiology of consciousness is to experimentally manipulate consciousness as a variable and then visualize the resultant functional brain changes with advanced imaging techniques. To begin investigation into this area, healthy volunteers underwent positron emission tomography scanning while listening to randomized word lists in both conscious and unconscious conditions. Following anaesthesia, subjects had no explicit memories. Nonetheless, subjects demonstrated implicit memory on a forced-choice test . These subsequent memory scores were correlated with regional brain metabolism measured (...) during encoding. Conscious recall and unconscious recognition memory demonstrated considerable anatomic overlap in correlating significantly with relative glucose metabolism in auditory verbal memory areas. However, only conscious recall correlated with mediodorsal thalamic nucleus activity; unconscious recognition memory did not. These findings suggest that conscious versus unconscious memory distinctions may depend on the presence or absence of correlated thalamic activity, and directly implicate the thalamus in the neurobiology of consciousness.

Animal ethics is generating growing interest both within academia and outside it. This book focuses on ethical issues connected to animals who play an extremely important role in human lives: companion animals, with a special emphasis on dogs and cats, the animals most often chosen as pets. Companion animals are both vulnerable to and dependent upon us. What responsibilities do we owe to them, especially since we have the power and authority to make literal life-and-death decisions about them? What (...) kinds of relationships should we have with our companion animals? And what might we learn from cats and dogs about the nature and limits of our own morality? The contributors write from a variety of philosophical perspectives, including utilitarianism, care ethics, feminist ethics, phenomenology, and the genealogy of ideas. The eighteen chapters are divided into two sections, to provide a general background to ethical debate about companion animals, followed by a focus on a number of crucial aspects of human relationships to companion animals. The first section discusses the nature of our relationships to companion animals, the foundations of our moral responsibilities to companion animals, what our relationships with companion animals teach us, and whether animals themselves can act ethically. The second part explores some specific ethical issues related to crucial aspects of companion animals' lives-breeding, reproduction, sterilization, cloning, adoption, feeding, training, working, sexual interactions, longevity, dying, and euthanasia.

We present an instrument developed to explain to students the concept of the personal ethical threshold (PET). The PET represents an individual’s susceptibility to situational pressure in his or her organization that makes moral behavior more personally difficult. Further, the PET varies according to the moral intensity of the issue at hand, such that individuals are less vulnerable to situational pressure for issues of high moral intensity, i.e., those with greater consequences for others. A higher PET reflects an individual’s greater (...) likelihood of adhering to the morally correct path, even in the face of high situational pressures (personal costs) and low moral intensity (collective importance). PET questionnaires were completed by 506 students representing eight business schools throughout the United States. Relationships between respondents’ PET and their gender, age, and major field of study, as well as the geographical location of their school, are explored. Results indicate that older students have higher PETs and that students attending schools in the northeastern part of the United States have lower PETs. These findings are discussed. It is argued that the PET instrument can be used to help students identify organizational pressures and intrapersonal processes that can impede their moral behavior in organizations. (shrink)

Posner & Raichle (1994) is a nice addition to the Scientific American Library and the average reader will both enjoy the book and learn a great deal. As an activeresearcher, however, I find the book disappointing in many respects. My two major disappointments are in the illusion of computation that is created throughout the volume and in the inadequate perspective of the presentation on visual attention.

Tato práce se zabývá možnými přístupy k etice sexuality, jejich klady i zápory. Etikou sexuality zde není míněno moralizování, stejně tak sexualitou není míněn pouze koitus, pohlavní chování je zde míněno v širším významu tedy včetně rozlehlé oblasti lidského svádění, okolků či otálení. Popsány jsou čtyři klasické přístupy k etice sexuality: tradicionalistický, romantický, marxisticko-feministický a liberální, avšak uvážen je i přístup antinatalistický, který vyplývá z asymetrického argumentu Davida Benatara uveřejněného v jeho práci Nebýt či být. Benatarův antinatalizmus totiž vytváří etiku (...) pohlavního chování, v níž pouze sex, který nevede k rozmnožení, může být morální. I když je tento pátý, antinatalistický přístup značně kontroverzní a zdaleka ne intuitivní, extrémnost jeho pozic se příliš neliší od tradicionalistického pohledu, v němž je morální pouze sex k rozmnožení vedoucí, tyto dva přístupy tak lze postavit do přímé opozice jako dvě krajní možnosti uvažování o etice pohlavního chování. Roli střední cesty v takovém řazení potom zaujme liberální přístup, který jako jediný etiku sexuality nevidí jako etiku odlišnou od jiných lidských činností. (shrink)

We treat companion animals according to one set of guidelines and so-called “meat animals” according to an opposing set of guidelines, despite the apparently significant similarities between the animals in question. I consider moral justifications offered for this disparity of treatment and show that this paradox reveals a mistake in our moral thinking. Generally, we group animals used in farming and free-living animals together as subject to the ethic of justice and distinguish both from companion animals, who are subject to (...) the ethic of care. I argue that animals used in farming, like companion animals, should be understood as within the sphere of care. (shrink)

This study of the patterns of the keeping of herpetofauna animals and associated animal welfare issues among secondary school pupils in the United Kingdom suggests that a large proportion of the animals kept as companion animals by this group are indigenous species. In comparison with purchased species, these captured animals, even those normally long-lived, appear to suffer a high rate of mortality. Relatively large numbers of escape- and food-related deaths among these animals imply that many are not furnished with suitable (...) vivaria or adequate care. Traded reptile and amphibian species were reported to have been kept by nearly 40% of the students who said they had kept herpetofauna, and the proportions of most taxa reflected their availability in shops. Data concerning students' opinions about their own care-knowledge appeared to support the general conclusion that students have much to learn about keeping reptiles and amphibians. These findings are considered in relation to issues of animnl welfare and herpetofauna conservation. Their ramifications for school-based education about reptiles and amphibians are also discussed.

PET studies using classical conditioning paradigms are reported. It is emphasized that PET studies show and not in learning paradigms. The importance of dissociating motor performance and learning deficits in human lesions studies is demonstrated in two exemplary studies. The different role of the cerebellum in adaptation of postural reflexes and learning of complex voluntary arm movements is discussed, [THACH].

In this article, I consider the question of whether having pets is morally permissible. However, I do so indirectly by considering three objections to the practice of having pets — what I shall call the ‘restriction of freedom objection’, the ‘property objection’, and the ‘dependency objection’. The restriction of freedom objection is dismissed relatively easily. The property objection also fails to show that having pets is morally impermissible. However, my consideration of this second objection does lead to (...) the conclusion that we ought to aim at changing existing legal systems and the majority of people's attitudes towards pets such that they are no longer considered to be the personal property of the humans in whose homes they are kept. But, while it is clear that we ought to aim at ending the practice of owning pets, it is not clear whether we ought to aim at ending the practice of keeping pets. Indeed, I do not to reach a definitive conclusion about the cogency of the dependency objection. However, I argue that this lack of clarity is of little concern at this time as our present moral obligations to pets are quite clear. (shrink)

Though there has been an array of methods to evaluate the extent of sarcoidosis, it is generally difficult to detect central nervous system involvement. Recently it has become accepted that 18F-FDG PET is more sensitive than gallium scintigraphy in finding sarcoid lesions, however its usefulness and limitations for detecting sarcoidosis in the central nervous system, especially in the spinal cord, has rarely been investigated. Two patients with pathologically confirmed sarcoidosis manifested spinal symptoms. We conducted 18F-FDG PET along with conventional imagings (...) before and after treatment. Abnormal FDG uptakes which could not be detected by gallium scintigraphy were shown in the spinal cords in both patients. These abnormal uptakes were diminished in accordance with clinical improvement after treatment. Our findings suggest that 18F-FDG PET is effective in detecting and tracking the activity of spinal sarcoidosis. (shrink)

Aesthetics is a crucial ecosystem service provided by biodiversity, which is believed to help improve humans’ quality of life and is linked to environmental consciousness and pro-environmental behaviors. However, how aesthetic experience induced by plants/animals influences the belief in the occurrence and significance of biodiversity loss among urban residents remains understudied. Thus, the current study aimed to examine how the diversity of pets and in-house plants affect urban residents’ belief in biodiversity loss in different scenarios of aesthetic experiences (positive (...) and negative aesthetic experiences at home due to plants/animals). Using the Bayesian Mindsponge Framework (BMF) analytics on a dataset of 535 Vietnamese urban residents, we found that the people’s aesthetic feeling about their house induced by plants/animals positively affects their belief in the occurrence and significance of biodiversity loss. The diversity of plants and pets also positively influences the level of biodiversity loss belief, but the effect is conditional on the aesthetic experience of the urban residents. Specifically, the positive impact of species diversity on the belief only exists when urban residents feel that their houses’ aesthetics are negatively affected by plants/animals. Moreover, the effect of pet diversity on biodiversity loss belief is less significant and reliable than that of plant diversity. These findings suggest that raising the houses’ aesthetics through in-house planting or pet ownership can potentially enhance biodiversity loss belief and subsequently build an eco-surplus culture among urban residents.

Using depth interviews and participant observation, the predominant metaphors that emerge in pet owners' relationships with theiranimals are pets as pleasures, problems, parts of self, members of the family, and toys. These metaphors as well as patterns of interacting with and accounting for pets, suggest vacillation between viewing companion animals as human and civilized and viewing them as animalistic and chaotic. It is argued that these views comprise a mixed metaphor needed to more fully understand our fascination with (...) pets. (shrink)

“Privacy as confidentiality” has been the dominant paradigm in computer science privacy research. Privacy Enhancing Technologies (PETs) that guarantee confidentiality of personal data or anonymous communication have resulted from such research. The objective of this paper is to show that such PETs are indispensable but are short of being the privacy solutions they sometimes claim to be given current day circumstances. Using perspectives from surveillance studies we will argue that the computer scientists’ conception of privacy through data or (...) communication confidentiality is techno-centric and displaces end-user perspectives and needs in surveillance societies. We will further show that the perspectives from surveillance studies also demand a critical review for their human-centric conception of information systems. Last, we rethink the position of PETs in a surveillance society and argue for the necessity of multiple paradigms for addressing privacy concerns in information systems design. (shrink)

This study explores ethnic variations in animal companion attachment among 133 students enrolled in a school of veterinary medicine. The 57 White and 76 African American participants completed surveys that included background information, several questions about their animal companions, and a pet attachment questionnaire .White students had significantly higher PAQ scores than did African American students . White students also had significantly more pets and more kinds of pets and were more likely to allow pets to sleep (...) on their beds . Although keeping pets is a universal cultural phenomenon, how that attachment is expressed may vary from culture-to-culture. This study explores possible explanations and implications for these variations. (shrink)
